Background
- Benign and self-limited condition of the epiploic appendages (fat-filled sacs along surface of colon and rectum)[1]
- Acutely inflamed due to torsion or venous thrombosis
- Mimics Appendicitis or Diverticulitis
- Most often found on abdominal CT during abdominal pain workup
- More than half occur in rectosigmoid colon
Clinical Features
- Abdominal pain
- May develop fever and leukocytosis
Differential Diagnosis
RLQ Pain
- GI
- Appendicitis
- Perforated appendicitis
- Peritonitis
- Crohn's disease (terminal ileitis)
- Diverticulitis (cecal, Asian patients)
- Inguinal hernia
- Mesenteric ischemia
- Ischemic colitis
- Meckel's diverticulum
- Neutropenic enterocolitis (typhlitis)
- Appendicitis
- GU
- Other
Evaluation
- CT abdomen with IV contrast
Management
Disposition
- Outpatient follow-up.
- Although recurrence is common the disease is self limiting and not life threatening.
Prognosis
- Complete resolution normally within 3-14 days
